This national standard specifies the minimum allowable value of energy efficiency, the targeted minimum allowable value of energy efficiency, the evaluating values of energy conservation and test method for three-phase distribution transformers.
This standard is applicable to off-circuit tap-changing oil-immersed distribution transformer with 30 kVA~1600 kVA rated capacity and dry-type distribution transformer with 30 kVA~2500 kVA rated capacity, which are both three-phase 10 kV.
This standard is not applicable to gas-filled transformer.
